The 650-17 NNF-12.5 is a notch filter with a diameter of 12.5 mm, manufactured by Iridian Spectral Technologies. This filter is designed to transmit light at a central wavelength (CWL) of 650 nm while blocking light at nearby wavelengths, making it ideal for applications that require narrow-band light isolation.
The filter is constructed with a base shape of a circle, and it has a thickness of 3 mm. It is made from UVFS MAL-1965 material, which is known for its excellent optical properties. The filter's coating, both on the front and back, is 'irr 650-17-nnf', which is specifically designed to enhance the filter's performance.
The 650-17 NNF-12.5 is shaped as a thin lens, which allows it to be easily integrated into various optical systems. The filter is currently in stock and can be purchased directly from the vendor's website.
